Abstract: (437 Views) |
| Ephippia Moina macrocopa hatching relates to the quality of nutrients received by the parent. Increasing the quality of the parent feed can improve the quality of the nutrient in eggs (ephippium) and can increase hatchability. This study was conducted to examine the addition of fatty acids in the feed through replacing rice bran suspension with fishmeal suspension on the quality and quantity of ephippia M. macrocopa. The treatment in this research was a substitution of rice bran suspension with fishmeal suspension by 0, 15, 30, and 45%. This study indicated that substitution of rice bran suspension with fishmeal suspension of 30% and 45% in Moina culture produced the same ephippia production but with a higher degree of hatching. Moreover, the substitution of rice bran suspension with fishmeal suspension by 30% increased the concentration of n-3 fatty acids (1.15%) in the egg of ephippia M. macrocopa. |
